Victoria Beckham has revealed she and the rest of the band - Emma Bunton, Mel C and Geri Halliwell - constantly go to Scary Spice Mel with their bedroom problems.
Victoria said: "If we have sex problems, we go to Mel B - she is like the doctor."
Mel - who has a nine-month-old baby, Angel Iris, with ex-boyfriend Eddie Murphy and an eight-year-old daughter, Phoenix Chi, with first husband Jimmy Gulzar - has always been rumoured to have a wild sex life.
In 2004, she sparked bisexual rumours when she was pictured kissing a film executive known only as Christine.
Mel - who is now married to movie producer Stephen Belafonte -also allegedly enjoyed lesbian threesomes with her friend Christa Parker and actress Elizabeth Rodriguez last year at her Los Angeles home.
Mother-of-two Christa claimed: "I had only had sex with a woman once before, but Mel was obviously very experienced with women. She is a great kisser.
Mel and I were very good friends. We saw each other almost every day and would have sex at least a couple of times a week."
